SPRING FOR BEDsTEADs.

Specitication forming part of Letters Patent No. 51,516. dated December 12, 1865.

To all whom it may concern.'

Be it known that I, DAVID MANUEL, of Newton, in the county of Middlesex and State ot' Massachusetts, have invented an Improved Spring for Bedsteads; and I do hereby declare the same to be fully described in the following specitication, and represented in the accompanying drawings, otl which- Figure l is a top view, and Figs. 2 and 3 are side elevations ot it, the saine also showing its application to a bedstead-slat.

The bo'dy A of the said spring is conoidal or conical in form, or, in other words, a conical or conoidal spiral, terminating at its apex in a straight extension, a. The base or lower coil ofthe spiral has a tangential prolongation, B, made in the form of an eye or socket, for

embracing the slat O. That portion b of such' eye which goes across that side of the slat which is opposite to that surface of it on which the base of the spring rests is carried somewhat back of the remaining parts c d of the eye, they standing at acute angles to it, this arrangement being as represented in the drawings, and for the purpose of better preventing the spring from tipping laterally7 on the slat.

The spring, made as specified, can readily be applied to a bedstead-slat, and answers as an excellent elastic support therefor.

The arrangement of the socket or eye tangential or approximately so with respect to the spring enables the spring' at its base when compressed to obtain a full or nearly circular bearing on the slat. The format-ion or construction of the eye in the manner described, viz., with its parts c d disposed at acute angles with the part b, is productive of advantage, as stated.

I claim- The combination as well as the arrangement ot' the eye B and the conoidal or conical spring A, substantially as specitied and as represented.

DAVID MANUEL.
